Global watchdog the Organisation for the Prohibition of Chemical Weapons (OPCW), which is overseeing the destruction of Syria's toxic arsenal, called on the government of President Basharal-Assad to pick up momentum in handing over the remaining chemicals.

Syria missed a deadline to transport the most toxic substances out of the country by December 31, loading the first batch of chemicals on to a Danish cargo vessel on Tuesday, a week late.

The Syrian government has until the end of March to hand over the so-called first priority chemicals, including around 20 tonnes of lethal mustard gas, and to the end of June to completely eliminate its chemical weapons programme.

"We are exhorting the Syrian government to intensify its efforts, so we can conclude the critical part of this mission absolutely as fast as the conditions allow," OPCW spokesperson Michael Luhan said on Wednesday.

"We are happy to see there is finally movement. We hope to see that that movement continues regularly now through the next few weeks, so we can get these chemicals out of the country as quickly as possible."

In transit
Syria declared 1 300 tonnes of chemical weapons to the OPCW, which won the Nobel Peace Prize last year, and is transporting them by road to the port of Latakia so they can be destroyed abroad.

Chemical weapons were likely used in five out of seven attacks investigated by UN experts in Syria, where a nearly three-year-old year civil war has killed more than 100 000 people, according to a UN investigation.

The most serious attack was on August 21, when hundreds of people died in a sarin gas strike in the outskirts of capital city Damascus.

That attack prompted the United States to threaten to use military force against Assad's regime, which it said was likely responsible.

The bulk of the chemicals will be processed on the Cape Ray, a 200m US cargo ship, which is being fitted with a portable hydrolysis system to neutralise around 560 tonnes of the most deadly toxins.

The remainder will go to commercial toxic waste processing plants, including one in England.
